Not exactly. It's how the dependencies got fulfilled.
It's probably a good thing though -- it _is_ a better choice because
it's much easier to deal with and much more versatile than the other
options; _especially_ than sendmail :)

No its better because you like it more. I think you have been pushing
for this since at least 1999 (2000 for sure).
Me I would like postfix :)

It *is* way better than sendmail but it *do* like postfix better too.

Someone has shamelessly used the fact exim was the MTA with the shortest
name to sneak this big change in.
